Answer 1

I goted a same problem in my project, I tryed this solutions about ProcessBuilder.directory(myDir) and the exec method from Runtime and all my trays failed..
It's make me understanding that the Runtime have a limited privileges just for the working directory and the sub directories of it.

So my solution is ugly but working very well.
I create a temporary .bat file in "runtime" in the working directory.
This file included two lines of commands:
1. Move to needed directory (cd command).
2. Do the command in need.
I call the exec from Runtime with my temporarily .bat file as command.
It's work for me very well!
